StackScope is a free public catalogue of indie launches. We find launches on Product Hunt, Hacker News and similar feeds, then crawl each site to detect its tech stack and score it for launch readiness: DNS, security headers, SEO basics. This page is what we saw on 20 April 2026; the live site may have changed since.

GrainLab is early-stage. Visible gaps: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on April 20, 2026. The site is hosted on GitHub Pages and served through Fastly. We've detected 6 technologies on this site, covering analytics, CDN, developer tools, and web fonts. The stack includes Vue.js, Fastly, and GitHub Pages.

It's one of 32 launches on this exact stack.
